Pinboard used for supporting tubes and cones



March 24, 1942. w. H. MILLER PINBOARD USED FOR SUPPORTING TUBES AND CONES Filed May 20, 1941 Patented Mar. 24, 1942 PlNBOARD USED FOR SUPPORTING TUBES AND CONES William H. Miller, Conyngham, Pa., assignor to Freeland Spool and Bobbin Corp., Hazleton, Pa., a corporation of Pennsylvania Application May 20, 1941, Serial No. 394,357

8 Claims.

This invention relates to certain new and useful improvements in pinboards used for support ing tubes and cones, the object being to provide a pinboard with means for releasing an arbor carried by the tube or cone when placed thereon and the construction herein illustrated is adapted to be used in connection with a construction of self-locking arbor as disclosed in the application of George B. Markle, Jr., filed March 7, 1941, Serial No. 382,247.

In the Markle application a self-locking arbor for tubes and spools or the like is disclosed in which spring arms are employed for locking the tube or the like on the arbor which can be released by a movable disc carried by the arbor, the object of this invention being to provide a pinboard with means for releasing the locking mechanism of the arbor when the tube or the like is placed in position on a pinboard, thereby saving the time required to independently release the arbor from the tube as the locking means is automatically released as the tube or the like is positioned on the pinboard to allow the arbor to be withdrawn from the tube or the like.

Another advantage obtained by using a pinboard with means for releasing the locking means is that the yarn is prevented from becoming soiled as the tube carrying the yarn is placed directly from the arbor on the pinboard.

Another advantage of using my ring-type pinboard in that it acts as locating means in finding the center of the tube in placing the tube on the pinboard.

In the drawing:

Fig. 1 is a plan view of a pinboard constructed in accordance with my invention.

Fig, 2 is an enlarged section through one of the pins and releasing means.

Fig. 3 is an enlarged vertical section through a pin with another form of releasing ring and a tube and arbor partly in position thereon.

Fig. 4 is a side view of a modified form of pin for the pinboard forming the centering and releasing means.

In the embodiment of my invention herein shown and described a conventional type of pinboard is illustrated consisting of a rectangular frame I having cross strips 2 carrying inverted U-shaped pins 3 forming the centering means for the tubes or the like carrying the yarn. In Figs. 1 and 2 I have shown a releasing means especially constructed so that it can be attached to a previously constructed pinboard, and in Fig. 3 I show releasing means to be manufactured with the pinboard, but it is of course understood that I do not Wish to limit myself to any particular construction of releasing means as my invention consists broadly in providing a pinboard with means for releasing the locking means of an arbor within a tube or the like when the tube carrying the yarn is placed in position on the pinboard.

In Figs. 1 and 2 the releasing means consists of an inverted cup-shaped member 4 having an annular flange 5 over which is arranged a releasing ring 6 with its lower edge in engagement with the flange and secured thereto by welding or the like. The releasing means is then pressed down over a pin 3 until the pin engages the bottom of the cup 4 which positions the releasing device on the pin at the proper distance from the upper end and to release the locking means of the arbor within the tube or the like.

In Fig. 3 a releasing means in the form of a ring I is welded or otherwise'secured to the pins of a pinboard when it is manufactured in such a position that it will engage the locking means of the arbor so as to release the locking means of the arbor in the tube or the like, as the tube is placed in position on the pinboard. This enables a locking means for arbors to be manufactured and used in connection with a pinboard without providing independent means for releasing the locking means of the arbor from the tube or the like, thereby enabling the use of a locking means between the arbor and the tube or the like without providing separate and independent means ior releasing the locking means between'the arbor and tube or the like. With the construction herein shown and described a locking means between the arbor and the tube and the like can be used and the tube disposed in position on the pinboard for its purpose and the arbor withdrawn from the tube without the use of any other releasing means.

In Figs. 2 and 3 Ishow a tube or the like 8 perforated to receive projection 9 carried by spring arm Ill mounted on an arbor H as the tube is positioned thereon for locking the tube to the arbor so that it will revolve with the arbor.

The spring arms are compressed to release the tube by a movable mounted apertured disc l2 which is engaged by the ring-like releasing means of the pinboard as the tube and arbor is placed in position thereon. The sliding movement of the disc I! is limited by a ring l3 carried by the arbor II.

In Fig. 4 I show a pin for a pinboard comprising a tube I4 having prongs l5 at its lower end bent outwardly to form the tube centering means the upper portion thereof forming the ring-like member to release the locking means of the arbor as it is positioned thereon.

This device is especially adapted to be used in connection with arbors having means for locking a tube or the like on an arbor as it is placed on the arbor, and while I am aware that the Markle application discloses means for releasing the locking means, my invention relates to a pinboard having means for releasing the locking means as the tube or the like is positioned thereon thereby eliminating the use of other releasing means and enabling the use of locking means between the arbor and tube Without any inconvenience as the locking means will be released as the tube is placed on the pinboard.

I claim:

1. In combination a pinboard, a locking" means for an arbor for tubes or the like and means carried by the pinboard for releasing the locking means as the tube or the like is placed in position on the pinboard.

2. In combination a pinboard for supporting tubes or the like containing yarn, a locking arbor for supporting the tube while yarn is being Wound thereon including yielding means for locking the tube on the arbor and means carried by the pins of the pinboard cooperating with the yielding locking means of the arbor to release the locking means as the tube is placed over the pins of the pinboard.

3. A pinboard having a ring-like member carried by the pins of the board for releasing an arbor from a tube or the like when placed over a pin.

4. A pinboard having a plurality of pins for centering and supporting tubes or the like, a releasing device carried by each pin, consisting of an inverted cup-shaped member carrying a ringlike member.

5. A pinboard having a plurality of pins for supporting and centering tubes or the like and a ring-like member carried by each pin having its outer end arranged beyond the end of the pin.

6. A pinboard having a releasing device arranged about each pin thereof for engagement with the locking means of an arbor carrying a tube or the like.

7. A pinboard having a plurality of pins and releasing means arranged about the pins and extending beyond the ends of the pins for releasing an arbor from a tube or the like when placed in position on a pin.

8. A pinboard having a ring-like member forming a portion of each pin thereof for locating the center of a tube and releasing the locking mechanism of the arbor as the tube is positioned on the pinboard.
